The U.K.'s House of Commons has rejected an amendment that would've offered shelter to 3,000 unaccompanied refugee children in Europe.

The amendment was authored by Lord Alfred Dubs, who as a child used a similar program to flee Nazi occupation before World War II. The proposal made it past the House of Lords but was narrowly defeated in the House of Commons 294-276.

Opponents of the proposal claimed admitting child refugees could incentivize child trafficking to get into Europe; the government vowed they would accept 3,000 children from refugee camps in the Middle East instead. The U.K. has already promised to accept 20,000 Syrian refugees by 2020.

But the government's plan still leaves refugee children in Europe at risk. Europol claims over 10,000 unaccompanied refugee children have gone missing in Europe over the past 18 to 24 months.
